China’s 1-octene copolymerized polyethylene market status and analysis of major companies in 2022

Polyethylene is an important synthetic resin with the characteristics of easy processing and molding, high thermal decomposition temperature and excellent comprehensive properties. At present, the comonomer types of polyethylene mainly include 1-butene, 1-hexene and 1-octene. The polyethylene produced with 1-octene as a comonomer has excellent performance and high added value. 1-Octene is an important linear olefin with the advantages of heat resistance, mechanical processing performance, transparency, softness, etc. The 1-octene copolymerized polyethylene products produced have excellent tear strength and damage strength. Advantages.

“2022-2026 1-Octene Copolymerized Polyethylene Industry In-depth Market Research and Investment Strategy Suggestions Report compiled by the Industrial Research Center It shows that at present, the production of linear low-density polyethylene (LLDPE) and high-density polyethylene (HDPE) usually uses gas phase method and slurry method. Due to the high boiling point of 1-octene, ethylene/1-octene copolymer products are mainly Produced using solution method.

The world’s major 1-octene copolyethylene manufacturers include Dow Chemical, DSM and Chevron Phillips. Dow Chemical used all 1-octene as comonomer in the low-pressure solution process and used Z-N catalyst to develop ATTANE ultra-low density polyethylene (VLD E) resin, which has better low-temperature flexibility and flex crack resistance. , which also has excellent optical properties, high tear resistance and other characteristics, has great development potential in high-demand film applications for harsh environments, and can be used to produce hot and cold water pipes and other durable materials.

The 1-octene copolymer polyethylene products produced by Chevron Phillips use a new blend of antioxidants and UV stabilizers, so they have a wide range of suitable processing temperatures, good processing fluidity, long-term UV stability, Excellent impact strength and good resistance to environmental stress cracking.

The 1-octene copolyethylene products produced by Nova Chemicals are produced using Sclairtech dual-reactor solution technology and a proprietary non-metallocene single-site catalyst. The products can be used to produce products such as highly transparent films.

Industry researchers said that 1-octene copolymerized polyethylene has excellent performance and is one of the high-end polyolefins. The product has great development potential and broad market application prospects. At present, domestic petrochemical companies such as Maoming Petrochemical, Shanghai Jinfei, and CNOOC have Chevron Phillips loop slurry process HDPE units, and Fushun Petrochemical has NOVA solution Sclairtech process LLDPE units, which are equipped to develop and produce ethylene/1-octene copolymerized polyethylene. Grade ability. However, due to China’s long-term reliance on imports of 1-octene products, it is difficult for Chinese petrochemical companies to produce related brands of products. In 2021, Daqing Petrochemical’s 1-octene and other α-olefin synthesis technology complete set of industrial pilot projects will be handed over, filling the domestic 1-octene production technology gap, and the overall technology has reached the internationally advanced level. In the future, Daqing Petrochemical can switch to produce 1-hexene, 1-octene, decene and other series of products under different working conditions. With the localization of 1-octene products in China, the output of 1-octene copolymerized polyethylene products is expected to grow.
